What Google Autocomplete tells us about countries

Together with my collaborators in the “Information Geographies” project at the Oxford Internet Institute, I have published a blogpost that analyses Google Autocomplete. This is seemingly a popular pastime these days, but unlike the maps I have seen so far, we don’t just map the most...

Reworked versions of my hexagonal population cartogram

In March, I have published a linked view display with a population cartogram of Switzerland (in German, in French). The occasion was a federal poll that convinced the majority of the voting population but didn’t gain support in enough many cantons. The cartogram has sparked...

Zurich Sky: Web-scraped sky colour over Zurich, Switzerland 2

Zurich Sky

… is the title of my most recent project. It’s a bit artsy, but I think some of the concepts behind it may also have practical applications in this world of ever more abundant webcam footage (maybe need to think a bit more on this...

Creating a hexagonal cartogram

Some weeks ago I visualised the Swiss cantons (states) and their population numbers using what information visualization scientists call a linked view. You can click through to the actual, interactive visualization: here in German or here in French. In what follows I’ll describe the steps of data preparation for this visualization....

In what follows I want to give a bit more detail about what...
